2017-07-11Introduce keyboard grabbing protocol for XwaylandOlivier Fourdan
This patch introduces a new protocol for grabbing the keyboard from Xwayland. This is needed for X11 applications that map an override redirect window (thus not focused by the window manager) and issue an active grab on the keyboard to capture all keyboard events.

Split out toplevel window like requests and events into a new interface called xdg_toplevel, and turn xdg_surface into a generic base interface which others extends. xdg_popup is changed to extend the xdg_surface. The configure event in xdg_surface was split up making xdg_surface.configure an event only carrying the serial number, while a new xdg_toplevel.configure event carries the other data previously sent via xdg_surface.configure. xdg_toplevel.configure is made to extend, via the latch-state mechanism, xdg_surface.configure and depends on that event to synchronize state. Other future xdg_surface based extensions are meant to also extend xdg_surface.configure for relevant window type dependend state synchronization.

2016-08-15xdg-shell: Add min/max size requestsOlivier Fourdan
Some application may wish to restrict their window in size, but xdg-shell has no mechanism for the client to specify a maximum or minimum size. As a result, the compositor may try to maximize or fullscreen a window while the client would not allow for the requested size. Add new requests "set_max_size" and "set_min_size" to xdg-shell so that the client can tell the compositor what would be its smallest/largest acceptable size, and that the compositor can decide if maximize or fullscreen is achievable, draw an accurate animation, etc. Signed-off-by: Olivier Fourdan <ofourdan@redhat.com> Bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=764413 Reviewed-by: Yong Bakos <ybakos@humanoriented.com> Reviewed-by: Mike Blumenkrantz <zmike@osg.samsung.com> Reviewed-by: Jonas Ådahl <jadahl@gmail.com>

xdg-foreign is a protocol meant to enable setting up inter surface relationships across clients. Potential use cases are out-of-process dialogs, such as file dialogs, meant to be used by sandboxed processes that may not have the access it needs to implement such dialogs. It works by enabling a client to export a surface, creating a handle for the exported surface. The handle, in form of a unique string, may be shared in some way with other clients (for example the provider of the file dialog) which can then import the exported surface.

2016-07-20tablet: Add pad support to the tablet protocolCarlos Garnacho
The pad's interface is similar to the tool interface, a client is notified of the pad after the tablet_added event. The pad has three functionalities: buttons, rings and strips. Buttons are fairly straightforward, rings and strips are separate interfaces with pointer-axis-like source/value/frame events. The two interfaces are effectively identical but for the actual value they send (degrees vs normalized position). Buttons are sequentially indexed starting with zero, unlike other protocols where a linux/input.h-style semantic event code is used. Since we expect all buttons to have client-specific functionality, an additional event tells the client when a given button index is not available, usually because the compositor assignes some function to it (e.g. mode switching, see below). Specific to the pad device is the set_feedback request which enables a client to set a user-defined string to display for an OSD on the current mappings. This request is available for buttons, rings and strips. Finally, the pad supports groups, effectively sets of button/ring/strip configurations. Those groups may have multiple modes each, so that users/clients may map several actions to a single element.

2016-07-20tablet: restrict the cursor surface to one per toolPeter Hutterer
The initial approach was to allow one surface to be re-used between tools, seats and even used together as wl_pointer cursor surface. This has a few drawbacks, most of which are related to managing the surface correctly in the compositor. For example, the same cursor surface could have two different hotspots. Animated cursors should animate independently rather than update at the same time. Furthermore: a client cannot know when a surface will cease being used as a cursor surface. The basic assumption of "after focus out" is an implementation detail in the compositor and unless the client unsets the cursor it is not guaranteed that the surface is released. This again makes sharing a surface less obvious - you cannot know if the wl_pointer surface is still in use when you set it for a new wp_tablet_tool. Avoid these headaches (and push some of them to the client) by simply restricting a wl_surface to be assigned to a single tool. For the 99% use case where we have one tablet with two tools (pen + eraser) this means we merely get two extra surfaces, and the two don't usually share the same cursor shape anyway. If sharing is absolutely necessary, a client may still opt to share the underlying wl_buffer.
